JabRef version JabRef-5.0-dev--snapshot--2018-11-06--master--5548f8f04 on Windows 8.1

• I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

Steps to reproduce the behavior:

1. create a new library
2. click on "save" (not "save as")
   • nothing happens (expected: file browser appears to select file, as for "save as")
